Nowadays, part tracking and traceability are elementary building blocks for success in the automotive and automotive supplier industry. On the one hand, systems are becoming technologically more complex, and on the other, development times are becoming shorter and shorter. In addition, quality requirements are constantly rising. Automotive manufacturers and suppliers apply various alphanumeric character sequences (e.g. serial or component numbers) and complex codes (mostly data matrix codes) to their products for this purpose, with which these can be monitored and traced at any time. Trotec Laser systems are an ideal tool to be able to reliably and quickly apply these codes and other contents to almost all materials that are used in the automotive industry while achieving a high-quality finish.
